Client Interfaces

There are only two client interfaces included in the base PostgreSQL distribution:
-
libpq is included because it is the primary C language interface, and because many other client interfaces are built on top of it.
-
ECPG is included because it depends on the server-side SQL grammar, and is therefore sensitive to changes in PostgreSQL itself.
All other language interfaces are external projects and are distributed separately. Table H-1 includes a list of some of these projects. Note that some of these packages might not be released under the same license as PostgreSQL . For more information on each language interface, including licensing terms, refer to its website and documentation.
